Hi KSK, the item will be posted using airmail from the United Kingdom. This shouldn't pose any problems, but some countries may charge some tax - you'd have to check with your customs - tell them it's for a camera strap.

Sorry Gordon, I made a mistake with the name. The Super Pro model is for MF cameras, the Pro Loop and Pro Strap have the correct attachment for DSLRs.

Yea, the cost issue is perfectly understandable.

To answer your question anyway, they are all OpTech models. It doesn't have that lining going along the edge of the current CL strap, this makes the edges a bit softer and the strap in general is larger and more stretchy, I think it is more comfortable. It's not a huge difference comfort wise but I thought it might be worth considering if you were in agreement with the advantages.
